What is wrong with my mesh? Freestyle render is glitchy and won't show certain lines
There is an object called &quot;Cube&quot; still in the way. You have set certain objects to Hide in Viewport (by clicking the eye icon in next to an object the Outliner), but not set them to Disable in Renders (by clicking the camera icon next to an object in the Outliner). To show the camera icons click on Filter (the funnel icon in the Outliner) and activate them under Restriction Toggles. Then you can also disable objects in your renders.
